Specification of Letters Patent,

Patenteu April 23, 1907.

Application filed September 20, 1905. Serial Ne. 279,210.

To all whom it may concern:

Be it known-that I, ASHLEY T. SHEWARD, a subject of the Kingof Great Britain, residing inthe city of St. Louis and State ofMissouri, have invented certain new and useful Improvements in Feed-Cutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. i

My invention relates to that class of cutting or chopping machines used for cutting hay, straw or sin lar feed for cattle or other stock, the object of the invention being to provide a machine in which-the feed ma be cut in both a transverse and longitudinaldirection in order that the straws being fed into the machine will be chopped into approximately uniform lengths; notwithstanding the fact that 'portions of them may lie crosswise of the other straws as they are fed to the cutter box. v 3

Figur-e I is a transverse section taken through a feed cutter constructed in acby which the feed, such as straW or hay, is

fed from the feed table to the chamber within the casing A.

3 designates a cutter bar located in the throatof the casing A adjacent to the feed rollers2" and which is provided with vertical slots 4 preferably of V- shape. The cutter bar is preferably surnounted by a slotted cutter plate 5, preferably of hardened steel, and against which the feed is cut as it passes over the cutter bar into the casing A. cutter plate may, however, be onitted and the feed be cut directly against the cutter bar.

'6 designates a shaft extending longitudinally through the casing A and adapted to be driven by power applied thereto in any suitable manner. This shaft has fixed to it within the casing, spiders having arms 7 and S.

9 are cutter blades carried by the spider arms 7 and adapted to be rotated so that their cutting edges will approach into close The form, carried by the spider arms 8 and 10- cated nearer to the shaft 6 than the cutter blades 9. The blades 10 move in a circular path causing the blades to approach the cutter bar 3 and move past it at a distance therefrom which is sufiicient to avoid contact of the blades with the feed delivered onto the cutter bar. Each of the blades 10 carries a plurality of transverse cutting knives 11 that are adapted to pass through the slots in the cutter plate 5 and the slots in the cutter bar 3 during the rotation of the blades 10, or which pass only through the slots in said cutter bar whenthe cutter plate is omitted. These cutting knives act to cut in a direction corresponding to the direction of introduction of the feed passed over the cutter bar 3, whereby any of the straws that' may lie cross-wise of the straws being fed straightforward into the casing will be cut by said knives 11.

By so positioning the blades 10 which carry the transverse cutting knives ll that they will not contact with the feed delivered onto the cutter bar, I provide for the cutting of the feed by the transverse knives in the desired manner and avoid expenditure of power that would be necessary to drive the blades 10 with cutting action, which is work there is no nece'ssity of their performing as the cutter blades 9 are amply suflicient to perform the cross cutting action in the machine.

In Fig. III I have shown a modification in which a blade 10' is provided with a cutting edge and also v carries the transverse cutting knives 11'. By so constructing the blades they may contain both the transverse and longitudinal cutting features and combine the elements of the blades 9 and the transverse cutting knives 11. In using the parts in this modified form the blades 10' would, it will be understood, be so disposed as to cause their cutting edges to travel into close proximity with the cutter bar 3 or its cutter plate 5.

I claim as my invention:

1. In a feed cutter, the combination of a slotted cutter bar, a slotted plate surnount- ICO IIO

a the material delivered onto said cutter ing said cutter bar, a blade, means by which said blade is rotatably carried, and a plurality of cutt'ng knves carried by said blade and arranged to operate through the Slots in said cutter plate and cutter bar, substantially as set forth.

2. In a feed cutter, the combinaton of a slotted cutter bar, a rotatable shaft, a cutter blade carried by said shaft and arranged to move in a circular path for cuttng action upon the material fed onto said cutter bar, a second non-cutting blade carried by said shaft and located nearer said shalt than said frst named blade, Whereby it is caused to move in a circular path Without action u on ar, and a plurality of cutting knives arranged transversely on said last named blade and adapted to operate through the slots in said cutter-bar, substantially as set forth.

red by shaft and located nearer said shalt than said frst named blade, Whereby t is caused to move in a circular path Without action upon the material delivered onto said 30 cutter bar, and a plurality of cutting knives arranged transversely on said last named blade and adapted to operate through the ?lot?1 in said cutter bar, substantially as set ort ASHLEY T. SHEWARD.
